58.1 Cry out with strength and do not hold back; lift up your voice like that of a trumpet, and proclaim their sins to my people and their lawless acts to the house of Jacob. 2 They seek me day by day and they will desire to, as a people, know my ways, who has done righteousness and has not abandoned the judgment of his God. 382. Improper fasts (58:2-6)
They ask me now for a righteous judgment, and they desire to approach God, 3 saying, Why is it that we fasted and you did not see it? We humbled our souls and you did not know it. For in the days of your fasts you find your wishes and you sting all your subjects. 4 You fast for judgments and fights, and you strike a humble person with fists. Why do you fast before me like today, for your voice to be heard with your shouting? 5 I have not chosen this fast and day for a man to humble his soul; not even if you bow your neck like a ring and spread sackcloth and ashes under yourselves; not even then shall you call it an acceptable fast. 6 I have not chosen such a fast as this, says Lord.

383. End injustice and you will be rewarded (58:6-8)
Instead, release every fetter of injustice; untie a knot of violent contracts of strangling, send those who have grown up away in forgiveness, and tear up every unjust document. 7 Break up your bread for a hungry person, and bring homeless poor people into your house. If you see a naked person, clothe him, and you will not overlook any of the families of your seed.

8 Then your light will burst forth early, and your healings will spring forth quickly, and your righteousness will go before you, and the glory of God will wrap around you. 384. Then God will listen to you (58:9-10)
9 Then you will cry out, and God will listen to you; while you are still speaking he will say, Look, I am here. If you remove a bond and finger-pointing and a word of grumbling from yourself, 10 and give the bread from your soul to the hungry (also we have humbled our soul), you will fill.385. Then your yearnings will be satisfied (58:10-12)
Then your light will rise in the darkness, and your darkness will be like mid-day. 11 And your God will be with you always, and you will be filled, just as your soul desires, and your bones will be cheered, and they will be like a drunken garden, and like a fountain which never lacks water. 12 And your deserts will be built up eternal, and your foundations will be eternal for a generation of a generation; and you will be called Builder of Hedges, and you will stop the paths in between.

386. Keep the Sabbath holy, and Lord will reward you (58:13-14)
13 If you turn your foot away from the Sabbaths to do your wishes on the holy day, and you call the Sabbath a delightful day, holy to God, you do not raise your foot upon a work, nor speak a word in anger from your mouth, 14 and you trust upon Lord, he may also lift you onto the good things of the land, and he will feed you the inheritance of Jacob your father, for the mouth of Lord has spoken these things.
